C Reactive Protein Level

C-reactive protein (CRP) is a marker of inflammation in the body. Elevated c-reactive protein levels can indicate infection, inflammation, autoimmune disease, or other health conditions. Monitoring CRP levels is crucial for diagnosing and managing various diseases, including cardiovascular disorders.

CRP levels above 3 mg/L are considered high and concerning, indicating a higher risk of cardiovascular disease. Levels between 1-3 mg/L are intermediate risk, while less than 1 mg/L is low risk. However, a single elevated CRP test is not enough to determine risk - two measurements taken 2 weeks apart should be averaged for a more accurate assessment.

A wide variety of inflammatory conditions, including infections, autoimmune disorders like rheumatoid arthritis and lupus, tissue injury, cancer, and obesity, can cause high CRP levels. A severe bacterial infection is the most common cause of markedly elevated CRP over 10 mg/L.
